Add a space before capital letters,

I would like a program designed the read a list of domain names, remove the extention ? (e.g .[login to view URL] .com .[login to view URL]), and add a space before the capital letters. ? See below for an example. ? I would paste in the program a list of domains (could be upto 2000 at once) [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] If you notice on the above, the domains with two or more words, have the first letter of the word in capitals, so the output I would want from the above example would be as below Air Cruise Airline Bookers? Airport Safety Airship Cruise Airship Cruises Airship Hotel Airship Hotels Airship Travel Ships Please note I would want the output to appear in the program and for me to be able to cut and paste into a seperate program (like excel)
